An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a combine body frame (moving vehicle body) for cutting and threshing grains such as soybeans, red beans, rice, wheat, buckwheat and the like, which is provided above the body frame 1. A glen tank 3 is provided on the side of a threshing device (not shown). 4 is a control unit provided on the front side of the Glen tank 3, 5 is a traveling device provided below the fuselage frame 1, and 6 is a cutting unit located on the front side of the threshing device 2 and the control unit 4.
The grain tank 3 is connected to the upper part of the grain storage cerealing device 10 connected to the terminal end of the first conveyor provided in the threshing device 2 (FIG. 3). The grain taken out by the first conveyor is temporarily stored in the Glen tank 3.
The Glen tank 3 is attached to a tank support frame 12 provided on the machine body frame 1 so as to be movable up and down. The Glen tank 3 is provided with a discharge portion 13 at the bottom, and the Glen tank 3 is configured to discharge the grain in the Glen tank 3 at a discharge position that is raised to a predetermined height from the work position where the mowing and threshing work is performed. Yes.
For example, the Glen tank 3 discharges the grains in the Glen tank 3 from the work position where the mowing and threshing work is performed to the discharge position where the discharge unit 13 is located above the top plate 14 of the Glen tank 3. It is configured as follows.

Note that the connection between the upper part of the grain storage cerealing device 10 and the grain tank 3 is, for example, like a shooter 15 that can be moved (in and out) freely provided in the discharge part 13 of the grain tank 3 described later. A shooter 16 that can be moved (entered / exited) is provided in the cerealing device 10, and the cerealing device for cereal storage so that the grain enters the grain tank 3 from the cereal storage cerealing device 10 at the work position where the harvesting / threshing operation is performed. 10 shooters 16 are automatically connected to the Glen tank 3 and when the Glen tank 3 is raised to the discharge position, the shooter 16 of the grain storage frying device 10 is retracted and the connection is automatically released. The details are omitted because it is not the gist of the present application.
An upper and lower cylinder 20 for raising and lowering the Glen tank 3 is provided between the Glen tank 3 and the body frame 1.
A shooter 15 that can be moved (in and out) is provided in the discharge part 13 of the Glen tank 3, and the shooter 15 is moved by an operation by an operating device (auger panel) 22 provided in the control part 4 to raise and lower the shooter 15 and the Glen tank 3. Is automated.

That is, when the discharge operation is performed by the operating device 22, the Glen tank 3 is automatically raised to a predetermined height, and then the shooter 15 is protruded from the side plate 23 of the Glen tank 3 to complete the preparation for discharge.
When the preparation for discharge is completed, the inlet of the transport vehicle or the storage tank is allowed to face below the shooter 15.
The discharge unit 13 is provided with a shutter 25 that can be opened and closed. When the shutter 25 is opened, the grain in the grain tank 3 starts to be discharged.
When the grain discharge is completed, the shooter 15 is automatically stored by the storage operation of the Glen tank 3 by the operating device 22, and the Glen tank 3 is automatically lowered to a working state of a predetermined height.
Therefore, a series of operations of raising the grain tank 3 and discharging the grain, storing the shooter 15 and lowering the grain tank 3 can be automated without manual operation, and work efficiency and labor of the operator are reduced.

Thus, the operation unit 22 includes a grain discharge switch 30 for automatically raising and lowering the Glen tank 3, projecting the shooter 15 and opening the shutter 25, and lowering the Glen tank 3 and storing the shooter 15. A storage switch 31 for automatically closing the shutter 25 is provided.
In this case, when the operating device 22 is also used as the operating device 22 for operating the discharge auger provided in the upper part of the vertical cerealing device connected to the Glen tank 3 of another model provided in the control unit 4, the parts are shared. Therefore, an additional device for operating means such as raising and lowering the Glen tank 3 is unnecessary, and the manufacturing cost is not increased.
Therefore, when the operation device 22 of the discharge auger of another model is shared, the grain discharge switch 30 becomes the “overhang” switch 30A, and when this “overhang” switch 30A is operated, the glen tank 3 is raised and the shooter 15 is moved. Next, the shutter 25 is opened and discharging is started.
The storage switch 31 becomes a “storage” switch 31A when the operation unit 22 of the discharge auger of another model is shared. When the storage switch 31A is operated, the shutter 25 is automatically closed and the shooter 15 is stored. Then the Glen tank 3 is lowered.
Reference numeral 32 denotes a controller.

Moreover, in this application, since the grain tank 3 is moved up and down to perform the grain discharging operation, the discharging time can be shortened as compared with other models using a discharging auger. This is preferable because it can suppress damage.
The shooter 15 can be arranged in any way, but as an example, the shooter 15 is provided with a base side discharge rod 35 movably in a mounting case 36 provided at the lower part of the Glen tank 3. The guide body 37 of the base side discharge rod 35 is fitted into the guide groove 38 of the mounting case 36 provided on the Glen tank 3 side. The base side discharge rod 35 is provided with a rack 39, and the gear 39 of the first motor 40 is engaged with the rack 39.
A front end discharge rod 42 is stacked on the upper surface of the base side discharge rod 35, and the gear 45 of the second motor 44 is engaged with the rack 43 of the front end discharge rod 42.
Therefore, the shooter 15 stores the base side discharge rod 35 with the front end side discharge rod 42 overlapped in the lower part of the Glen tank 3 and rotates the first motor 40 in the forward direction so that the base side discharge rod 35 is moved with respect to the Glen tank 3. Then, the second motor 44 is rotated forward to move and extend the distal end side discharge rod 42 with respect to the base side discharge rod 35 to be in a discharged state. And the 2nd motor 44 and the 1st motor 40 are each reversely rotated, and the shooter 15 puts the front end side discharge rod 42 on the base side discharge rod 35 and stores it in the lower part of the Glen tank 3.

The shutter 25 of the discharge unit 13 has a shutter 25 of the discharge unit 13 disposed below the Glen tank 3 fitted to the base side discharge rod 35 of the shooter 15, and a shutter opening / closing cylinder 46 is attached to the shutter 25. Then, the shutter 25 is opened and closed by the shutter opening / closing cylinder 46.
Further, the operation of the grain discharge switch 30 automatically raises the grain tank 3 and the shooter 15 extends and the shutter 25 opens, and the operation of the storage switch 31 lowers the grain tank 3 and stores the shooter 15 and the shutter 25. For example, if the grain discharge switch 30 and the storage switch 31 are simultaneously operated for a predetermined time on the assumption that the automatic closing can be performed by independent operation of the grain discharge switch 30 and the storage switch 31, the Glen tank 3 is automatically lifted to automatically project the shooter 15 and open the shutter 25. When the discharge is completed, the shooter 15 is stored, the shutter 25 is closed, and the Glen tank 3 is automatically lowered until it is lowered. Therefore, it is possible to select an operation form according to the working state, and to improve operability and workability.

That is, not only automation of the work by the individual operation of the grain discharge switch 30 and the storage switch 31 but also the operation of the grain discharge switch 30 and the storage switch 31 at the same time for a predetermined time, the upward discharge operation of the Glen tank 3 It is possible to automate the descending and storing work, select an operation form according to the work state, and improve operability and workability.
A grain presence / absence detection sensor 50 is provided in the lower part of the Glen tank 3 or the shooter 15. The grain presence / absence detection sensor 50 detects the presence / absence of grain in the grain tank 3 or the shooter 15 (FIG. 8).
That is, the grain discharge switch 30 (the “overhang” switch 30A) automatically raises the glen tank 3, overhangs the shooter 15, and opens the shutter 25. Or the presence or absence of the grain of the shooter 15 is detected.
Therefore, the worker can accurately determine the state of the Glen tank 3 that has been raised and perform the discharge operation.
The grain presence / absence detection sensor 50 is constituted by a contact type or non-contact type sensor.

Thus, the grain discharge is automatically performed by the discharge switch 51 provided separately from the grain discharge switch 30 (“overhang” switch 30A), and when the grain presence / absence detection sensor 50 detects that there is no grain, Even if the operation device 22 is not operated, the shutter 25 is automatically closed, the shooter 15 is retracted, and the Glen tank 3 is lowered (FIG. 9), which improves operability and workability. is there.
Moreover, since the shutter 25 is automatically closed and the shooter 15 is retracted, grain spillage is prevented.
That is, even if the grain presence / absence detection sensor 50 detects that there is no grain and confirms the end of the discharge operation, there is a slight remaining grain in the Glen tank 3, and this residual grain Particle spillage can be prevented by automatically closing the shutter 25 and retracting the shooter 15.
Further, when the grain discharge switch 30 (“overhang” switch 30A) automatically discharges the grain and the grain presence / absence detecting sensor 50 detects that there is no grain, the operation unit 22 is not operated. The shutter 25 may be automatically closed, the shooter 15 may be retracted, and the Glen tank 3 may be lowered.

Further, when an arbitrary operation automation operation such as simultaneous operation of the grain discharge switch 30 and the storage switch 31 is performed and the parking brake 55 is operated (FIG. 10), the Glen tank 3 is automatically raised to a predetermined height. When the grain is discharged, and the grain discharge is completed, the shooter 15 is automatically stored, the glen tank 3 is lowered, and the discharging operation is automated.
For this reason, it is possible to automate the discharge operation, omit the operation such as checking the Glen tank 3 at a high position, and prevent an erroneous operation of running the machine body during the discharge operation, thereby improving safety.
Moreover, the start of the automatic discharge operation is changed to simultaneous operation of the grain discharge switch 30 and the storage switch 31, and the operation of the discharge switch 51 provided separately raises the glen tank 3, extends the shooter 15, and opens the shutter 25. The shooter 15 may be stored, the shutter 25 may be closed, and the glen tank 3 may be lowered by detecting the absence of a grain by the grain presence / absence detection sensor 50 (FIG. 11).

That is, even when the grain discharge switch 30 and the storage switch 31 are simultaneously operated from the ascending / discharging operation of the Glen tank 3 to the descending storage operation of the Glen tank 3 by any work automation operation such as simultaneous operation for a predetermined time. When the presence / absence detection sensor 50 detects the absence of the grain, setting the glen tank 3 to perform the lowering and storing operation not only improves the operability and workability but also ensures the lowering and storing operation of the glen tank 3. It is possible to carry out and is suitable.
In addition, since the automatic discharge operation is started by a single operation of the discharge switch 51 instead of the simultaneous operation of the grain discharge switch 30 and the storage switch 31, the operation becomes easy.
Further, when an automatic discharge operation such as simultaneous operation of the grain discharge switch 30 and the storage switch 31 is performed, the storage of the shooter 15 and / or the detection of the absence of the grain by the grain presence / absence detection sensor 50 is performed. Alternatively, in the storing operation at the start of the descending of the Glen tank 3, a time lag of a predetermined time is set and operated.
Therefore, an accident or the like in which the shooter 15 or the Glen tank 3 contacts the discharge destination (container, truck, etc.) T after the completion of the discharge operation is avoided, and damage to the shooter 15 or the like is prevented.

That is, for example, when the storage operation is set so that the glen tank 3 is lowered while housing the shooter 15, the discharge operation time can be shortened, but the storage operation is performed immediately after the grain discharge in the glen tank 3. When the shooter 15 is started, the shooter 15 or the Glen tank 3 may come into contact with the discharge destination T. By setting a time lag of a predetermined time between the completion of the grain discharge in the Glen tank 3 and the start of the storing operation, Damage to the shooter 15 and the like can be avoided.
The shooter 15 is configured such that the entire length of the shooter 15 can be adjusted or switched (FIG. 12).
Therefore, the projecting position of the shooter 15 can be changed, so that the operability and workability of the discharge work can be improved.
In this case, the first motor 40 and the second motor 44 are operated by the shooter extension switch 56 or the shooter reduction switch 57 so as to adjust the overhang amount (FIG. 13).

Further, the projecting position may be switched so as to project to a predetermined position and then further project.
For example, when the shooter extension switch 56 or the shooter reduction switch 57 is operated, the first motor 40 and / or the second motor 44 are operated by a certain amount, and the base side discharge rod 35 or the tip side discharge rod 42 is expanded or contracted stepwise. You may make it (FIG. 13).
The shooter 15 is provided with an obstacle detection means 60 for detecting an obstacle near the tip of the shooter 15 (FIG. 14).
The obstacle detection means 60 prevents the shooter 15 from approaching and contacting the discharge destination (container, truck, etc.) T (FIG. 3) and preventing the shooter 15 and the discharge portion 13 from being damaged.
The shooter 15 is configured to be swingable (swingable) in the width direction of the shooter 15 with respect to the glen tank 3 by operating the shooter rotation motor 61 by the overhang position changeover switch 62 (FIG. 15).
Therefore, since the shooter 15 is swung in the width direction, the grains can be evenly discharged to the discharge destination (container, truck, etc.).

When it is detected on the display panel (multi-eye) 66 composed of liquid crystal or the like of the control unit 4 that the aircraft is tilted, the rise of the Glen tank 3 is stopped, and the tilt of the aircraft and the rise of the Glen tank 3 are stopped. The work state is configured to be displayed (FIG. 16).
Accordingly, it is possible to prevent the aircraft from falling or being damaged by avoiding the discharging operation in the inclined state.
The inclination of the airframe is configured to be detected by an inclination sensor (vehicle body slope sensor) 65. The inclination sensor 65 detects the inclination of the aircraft on an inclined ground, and also detects a case where one side of the aircraft is submerged in a wetland or the like, even if the slope is not inclined. In addition, the tilt direction of the aircraft is detected including not only the left-right direction but also the front-rear direction tilt.
67 is a tank raising position detection sensor.
In addition, although each above-mentioned Example is demonstrated separately in order to make an understanding easy, these Examples can be combined variously, respectively, FIG. 18 is combining the sensor and switch of each Example. FIG.

(Operation of Example)
The aircraft is advanced by sitting on the control unit, the cereals in the field are harvested by the reaping unit 6, the harvested cereals are supplied to the threshing device 2 and threshed, and the threshed grains are side portions of the threshing device 2. Is stored in the Glen tank 3 provided in the tank.
When a predetermined amount of grain is stored in the Glen tank 3, the machine body is moved to the vicinity of the discharge destination (container, truck, etc.) T.
Next, since the Glen tank 3 is attached to the tank frame tank support frame 12 provided in the machine body frame 1 so as to be movable up and down, the Glen tank 3 is raised and the discharge portion 13 of the Glen tank 3 is set to the discharge destination T. The shooter 15 is faced, and the shutter 25 is opened and discharged.
In this case, since the shooter 15 is provided in the discharge part 13 of the Glen tank 3 so that it can freely enter and exit (extend / contract), the Glen tank 3 is raised and the shooter 15 is extended to perform the discharging operation. Since the rise of the Glen tank 3 is automatically performed by the operation unit 22 provided in the control unit 4, when the discharge operation is performed by the operation unit 22, the Glen tank 3 is automatically raised to a predetermined height, The shooter 15 is projected outward from the side plate 23 of the glen tank 3, and the discharge is started.

Next, when the grain discharge is finished and the storage operation of the glen tank 3 is performed by the operating device 22, the shooter 15 is automatically stored, and when the shooter 15 is stored, the glen tank 3 is put into a working state at a predetermined height. Automatically descend.
Therefore, a series of operations of raising and discharging the Glen tank 3 and storing and lowering can be automated without individual manual operations, thereby reducing work efficiency and labor of the operator.
Thus, the operation unit 22 includes a grain discharge switch 30 for automatically raising and lowering the Glen tank 3, projecting the shooter 15 and opening the shutter 25, and lowering the Glen tank 3 and storing the shooter 15. Since the storage switch 31 for automatically closing and closing the shutter 25 is provided, when the grain discharge switch 30 is operated, the glen tank 3 is automatically raised to project the shooter 15 and automatically the shutter 25. When the storage switch 31 is pressed after the discharging operation is completed, the shutter 25 is automatically closed, the shooter 15 is stored, and the glen tank 3 is further lowered to the original position. .

Therefore, the discharging operation can be automated by the discharging operation by the grain discharging switch 30 and the storing operation by the storage switch 31, and the work efficiency and the labor of the operator are reduced.
The grain presence / absence detection sensor 50 is provided in the lower part of the grain tank 3 or the shooter 15, so that the presence / absence of the grain in the grain tank 3 or the shooter 15 is detected by the grain presence / absence detection sensor 50. Then, the operator can accurately determine the state of the Glen tank 3 that has been raised and perform the discharge operation.
In this case, when the grain presence / absence detection sensor 50 detects that there is no grain, the shutter 25 is automatically closed without operating the operation unit 22, the shooter 15 is stored, and the Glen tank 3 is lowered. Since it is configured, if the grain discharge switch 30 is used to start the discharge operation, the operation can be automatically performed until the glen tank 3 is lowered, the operability and workability are improved, and the shutter 25 is automatically closed. , Prevent grain spills.

That is, the automatic discharge operation is started by raising the Glen tank 3 and projecting the shooter 15 and opening the shutter 25 by operating the grain discharge switch 30. By detecting, the storage of the shooter 15, the closing of the shutter 25, and the lowering of the Glen tank 3 can be automatically performed until the Glen tank 3 is lowered, so that the operability and workability can be improved. Since the shutter 25 is automatically closed, grain spillage is prevented.
Also, for example, if the grain discharge switch 30 and the storage switch 31 are simultaneously operated for a predetermined time on the premise that independent operation of the grain discharge switch 30 and the storage switch 31 is possible, the Glen tank 3 is automatically raised. The automatic operation of automatically projecting the shooter 15 and opening the shutter 25 and automatically closing the shooter 15 and closing the shutter 25 and automatically lowering the glen tank 3 is set when the discharge is completed. When individual operations of the grain discharge switch 30 and the storage switch 31 are selected, an automatic operation suitable for the work condition becomes possible, and both work eligibility and workability improvement by automation of the operation can be achieved. The operation of discharging work can be fully automated by operating the grain discharging switch 30 and the storage switch 31 at the same time for a predetermined time. Can choose work mode is to improve the operability and workability.

Further, for example, when an arbitrary operation automation operation such as simultaneous operation of the grain discharge switch 30 and the storage switch 31 is performed and the parking brake 55 is operated, the Glen tank 3 is automatically raised to a predetermined height. When the grain discharge is completed and the grain discharge is completed, the shooter 15 is automatically stored and the glen tank 3 is lowered to automate the discharge operation. The operation such as checking the Glen tank 3 at the position is omitted, and the erroneous operation of running the machine body during the discharging operation is prevented, thereby improving the safety.
In this case, since it is set to start storing the shooter 15, closing the shutter 25 and lowering the Glen tank 3 by detecting the absence of the grain by the grain presence / absence detection sensor 50, the inside of the Glen tank 3 or the shooter The presence / absence of 15 grains can be detected by the grain presence / absence detection sensor 50, and the descending operation of the glen tank 3 can be reliably automated.

Thus, when the storage operation of the individual storage switch 31 automates part or all of the storage of the shooter 15 and the closing of the shutter 25 and the lowering of the Glen tank 3, or between the grain discharge switch 30 and the storage switch 31. When part or all of the storage of the shooter 15 and the closing of the shutter 25 and the lowering of the glen tank 3 are automated by simultaneous operation, or the detection of the absence of grain by the grain presence / absence detection sensor 50, When the storing operation is automated, such as when the shutter 25 is closed and part or all of the descending of the Glen tank 3 is automated, a time lag of a predetermined time is set and operated when the storing operation is performed.
Therefore, an accident or the like in which the shooter 15 or the Glen tank 3 contacts the discharge destination (container, truck, etc.) T after the completion of the discharge operation is avoided, and damage to the shooter 15 or the like is prevented.
That is, for example, when the storage operation is set so that the Glen tank 3 is lowered while housing the shooter 15, the discharge operation time can be shortened, but the storage operation is performed immediately after the grain discharge in the Glen tank 3. When the shooter 15 is started, the shooter 15 or the Glen tank 3 may come into contact with the discharge destination T. By setting a time lag of a predetermined time between the completion of the grain discharge in the Glen tank 3 and the start of the storing operation, Damage to the shooter 15 and the like can be avoided.

Thus, when the grain discharge switch 30 and the storage switch 31 are operated simultaneously for a predetermined time to automate part or all of the storage of the shooter 15, the closing of the shutter 25, and the lowering of the glen tank 3, the grain discharge switch Instead of simultaneous operation of the storage switch 30 and the storage switch 31, a part or all of the storing operation of the discharge unit 13 can be automated by a discharge switch 51 provided separately.
Therefore, since the start of the automatic discharge operation is performed by a single operation of the discharge switch 51 instead of the simultaneous operation of the grain discharge switch 30 and the storage switch 31, the operation becomes easy.
When the storage operation by the operation of the discharge switch 51 is performed, if a time lag of a predetermined time is set in advance and the storage operation is performed, the shooter 15 and the Glen tank 3 are discharged to the discharge destination (container, truck, etc.) ) Avoid accidents that come into contact with T and prevent damage to the shooter 15 and the like.
That is, for example, if the automation of the storing operation is set so that the glen tank 3 is lowered while housing the shooter 15, the discharging operation time can be shortened, but immediately after the grain discharge in the glen tank 3 is performed. When the storage operation is started, the shooter 15 and the Glen tank 3 may come into contact with the discharge destination T, but a time lag of a predetermined time is set between the completion of the grain discharge in the Glen tank 3 and the start of the storage operation. As a result, damage to the shooter 15 and the like can be avoided.

Thus, when the operation device 22 is also used as the operation device 22 for operating the discharge auger provided on the upper part of the vertical cerealing device connected to the Glen tank 3 of another model, the parts can be shared, and the Glen tank 3 can be used. An additional device for operating means such as raising and lowering is unnecessary, and the manufacturing cost is not increased.
Therefore, when the operation device 22 of another type of discharge auger is also used, the grain discharge switch 30 becomes the “overhang” switch 30A, and when this “overhang” switch 30A is pressed, the glen tank 3 is raised and the shooter 15 is moved. Next, the shutter 25 is opened and discharging is started.
Further, the storage switch 31 becomes a “storage” switch 31A when the operation device 22 of another type of discharge auger is also used. When the “storage” switch 31A is pressed, the shutter 25 is automatically closed and the shooter 15 is closed. Store and lower the Glen Tank 3.
Thus, when the shooter 15 of the Glen tank 3 energizes the first motor 40 and rotates the gear 41, the tip side discharge rod stacked on the base side discharge rod 35 by the action of the rack 39 of the base side discharge rod 35. 42 is projected outward from the side plate 23 of the grain tank 3.

Next, the tip side discharge rod 42 is moved and overhanged with respect to the base side discharge rod 35 by the rack 43 of the tip side discharge rod 42 and the gear 45 of the second motor 44.
When the discharge operation is completed, the second motor 44 and the first motor 40 are reversed, and the shooter 15 stores the tip side discharge rod 42 on the base side discharge rod 35 and stores it in the lower part of the Glen tank 3.
Since the shooter 15 is configured so that the entire length of the shooter 15 can be adjusted or switched, the projecting position of the shooter 15 can be changed, and the operability and workability of the discharge work can be improved.
In this case, the base side discharge rod 35 or the tip side discharge rod 42 can be expanded and contracted by operating the first motor 40 and / or the second motor 44 by the shooter extension switch 56 or the shooter reduction switch 57. Thus, the shooter 15 can be positioned in an optimum state.
Further, when the shooter extension switch 56 or the shooter reduction switch 57 is operated, the first motor 40 and / or the second motor 44 are actuated by a certain amount, so that the base side discharge rod 35 or the tip side discharge rod 42 is expanded and contracted stepwise. The position of the shooter 15 can be switched with respect to the discharge destination T.

Since the shooter 15 is provided with an obstacle detection means 60 for detecting an obstacle near the tip of the shooter 15, the obstacle detection means 60 causes the shooter 15 to approach the discharge destination (container truck, etc.) T. Thus, contact is prevented, and damage to the shooter 15 and the discharge unit 13 is prevented.
Since the shooter 15 is configured to swing (swing freely) in the width direction of the shooter 15 with respect to the Glen tank 3, the shooter 15 is widened when the grain in the Glen tank 3 is projected to the discharge destination T. It can be swung in the direction, and the grain can be discharged to the discharge destination T evenly.
The control unit 4 is provided with a display unit (multi-eye) 66 composed of liquid crystal or the like. When it is detected that the aircraft is tilted, the rise of the Glen tank 3 is stopped, and the tilt of the aircraft and the rise of the Glen tank 3 are prevented. Since the stop is displayed on the display unit 66, the operator can visually grasp the display unit 66 to easily grasp the state of the airframe during the discharge work and avoid the discharge work in the inclined state to prevent the airframe from being overturned or damaged. Can be prevented.
Since the inclination of the airframe is detected by the inclination sensor 65, the inclination sensor 65 detects that the airframe is inclined due to the influence of the inclination of the farm field. Can be detected, and it is possible to prevent the aircraft from falling or damaging by avoiding the discharge work in the inclined state.

In addition, when the tilt sensor 65 detects the tilt of the airframe of the pitching mechanism or the rolling mechanism, the tilt direction of the airframe can be detected not only in the left-right direction but also in the front-rear direction. .
Therefore, in the present application, it is important that the ascending operation, the discharging operation, and the storing operation of the Glen tank 3 are automated, the operation of starting and ending the automatic discharging operation and the configuration of the operation means are arbitrary, and the grain discharging The configuration is not limited to the switch 30 and the storage switch 31, the “overhang” switch 30A, the “storage” switch 31A, the discharge switch 51, and the like.
Each of the above-described embodiments is illustrated and described separately or mixed for easy understanding. However, these embodiments can be combined in various ways, and these expressions can be used for configuration and operation. However, there is a case where a synergistic effect is obtained.
